Abstract (en)
[origin: US2020231503A1] Self-consolidating geopolymer compositions utilizing fly ash and inorganic mineral including alkaline earth metal oxide as cementitious reactive components and include cement set retarder. The alkaline earth metal oxide is preferably calcium oxide (also known as lime or quicklime) and/or magnesium oxide. The inorganic minerals including alkaline earth metal oxide have an alkaline earth metal oxide content preferably greater than 50 wt. %, more preferably greater than 60 wt. %, even more preferably greater than 70 wt. %, and most preferably greater than 80 wt. %, for example greater than 90 wt. %. The cementitious reactive powder may optionally also include one or more aluminous cements and one or more source of calcium sulfates. The cementitious reactive powders are activated with an alkali metal chemical activator selected from alkali metal salt and/or alkali metal base. Methods for making the compositions are also disclosed.
